Abstract (en)
An actinic radiation sensitive polymer composition containing (a) a polyimide precursor obtainable by the interaction of an amine compound having a photocrosslinking group with carboxyl groups of a poly(amic acid) chain, and (b) a photoinitiator and/or photosensitizer, in which the degree of imidization Ia is 0.03 ≤ Ia ≤ 0.6, has the characteristic features of both good stability of viscosity with lapse of time and good photosensitive performance.
